L RR = 1 2 H F α µf α µ 1 4 F µ νf µ ν + 1 2g ɛαβ F αβ. Hence, we have shown the S-duality at the Poisson level for a D3-brane in R-R and NS-NS backgrounds.

23 Coupling Constant Notice that the need of two independent parameters (g G, θ ) or (g G, θ) can be seen only if higher order terms are included. At the lowest order, we can scale the gauge fields so that the R-R action has g G = g G and θ = θ.
24 Double Scaling Limit The double scaling limit of NS-NS is: l s ɛ 1/4, g s ɛ 1/2, B µ ν 1, g αβ 1, g µ ν ɛ.
25 Double Scaling Limit The double scaling limit of NS-NS is: l s ɛ 1/4, g s ɛ 1/2, B µ ν 1, g αβ 1, g µ ν ɛ. The double scaling limit of R-R is: l s ɛ 1/2, g s ɛ 1/2, B µ ν 1, g αβ 1, g µ ν ɛ.
26 Double Scaling Limit The double scaling limit of NS-NS is: l s ɛ 1/4, g s ɛ 1/2, B µ ν 1, g αβ 1, g µ ν ɛ. The double scaling limit of R-R is: l s ɛ 1/2, g s ɛ 1/2, B µ ν 1, g αβ 1, g µ ν ɛ. Despite the fact that the string coupling g s is large for the R-R theory when it is small for the NS-NS theory, the decoupling of the D3-brane from the bulk in the Seiberg-Witten limit ensures that its S-dual picture also has an effective world-volume theory decoupled from the bulk.
